Get value of updated field for notification

[Bidduam]

I would like to be able to generate a notification when someone returns an asset. 

Wondering how I can automate it to the correct person after their name has been removed from the field already.

EG: 

Joe Bloggs is the person in the assigned_to field for asset xyzabc

Joe returns the asset and is removed from the field (it remains blank) and the asset is updated, at this point I'd like a notification sent to Joe Bloggs advising that he has returned the asset - sort of like a receipt in case later someone asks him where it is, he can prove he returned it.

Ideas?

please use previous object in BR script

(function executeRule(current, previous /*null when async*/) {
gs.eventQueue('asset.assigned.removed', current, previous.assigned_to.email.toString());
})(current, previous);

Thank you very much @Ankur Bawiskar that worked perfectly 🙂

@Ankur Bawiskar Do you know of a way to prompt for an email address that can then be used to send the notification to? In this case it would be to add a personal email address for someone who is leaving the organisation.

In BR you can write something like this and call event in notification.

Feel free to mark both solution as correct
